Double axle

from Wikipedia, the free encyclopedia

As a double axle was in the traffic law of the distance between two axes of more than 1 m and less than 2 m defined. In Germany , Section 34 (4) No. 2 of the current StVZO uses the term double-axle load, which applies to motor vehicles with less than 1.8 m center distance. If the center distance between two axles is less than 1 m, it is also referred to as a tandem axle.


Axles at a very short distance are needed to increase the statutory limitation of the load capacity of the individual axle. In the case of the double axle, a distinction is made with regard to the suspension (together with the rigid axle and leaf springs / individual trailing arms) and the steerability (unguided / steerable). In the case of driven double axles, one also speaks of a double axle assembly. The Mercedes-Benz LP 333 from 1958, which is regarded as the forerunner of today's multi-link vehicles in Germany, was equipped with double- axle steering. Kässbohrer developed tandem trailers with a compensating hub as early as 1937; In 1965, Müller-Mitteltal presented the tandem trailer with a flatbed and body.
